LEOPOLD BERTSOHE, OF ALLEGHENY, PENNSYLVANIA.

Letters Patent No. 98,912, dated January 18, 1870.

*CASTER FOR FURNITURE.

The Schedule referred to in these Lette'rs Patent and making part of the name.

To whom it may concern:

Drawings.

'the caster and leg combined and in readiness for use,

the leg having been fully lowered into the socket, and the eccentrics having, by their own gravity, fallen into their natural position.

This invention relates to improvements in casters; and i It consists in combining, with the leg of a table, bureau, &c., acaster, provided with a cylindrical socket, the. socket-piece having eccentric lugs, or their equivalent, to register with slots formed in the surface of the leg, as will be more fully hereinafter described.

Similar letters of reference indicate like parts in each of the figures.

A represents the leg of any article of furniture to which it is desired to attach my improved caster.

a a are slots cut in the surface, as clearly shown in fig. 1 of the drawings, for the purpose of admitting eccentrics G.

B G D is a caster-wheel, and its usual adjuncts, the pivot D, however, being only of suflicient length to pass through the bottom plate of the socket E.

E is a cylindrical socket, having vertical slots directly opposite each other, within which are hung the eccentrics G and-arms H.

Instead of having separate slots a a, a single slot may be cut the entire circumference of the leg.

The operation may be explained as follows:

When it is desired to combine the caster with the leg, the eccentrics G are thrown out by lifting the arms H, as clearly illhstrat-ed in fig. 1. The caster can then be pushed on, when the eccentrics and arms will, by their own gravity, fall into their natural position, as shown in-fig. 2, and the caster and leg become firmly locked together.

Vhen it is desired to detach the caster, it is only necessary to throw the eccentrics G out of slots a by lifting arms H. v Y

The advantages that I claim are, among others, that it can be readily joined or detached; that it will not fall off when lifted from the floor; that it will not split the leg to which it has been joined, as is frequently the case with the ordinary casters now in use.

. Having thus described my invention,

What I claim as new, and desire to secure by Letters Patent of the United States, is-

1. The cylindrical socket E, in combination with one or more eccentrics G, said eccentrics with or without arms H, as herein shown and described, and for the purpose set forth.

2. The leg A, having one or more slots, or a single annular slot, in combination with eccentrics G and socket'E, all as shown and described, and. for the purpose set forth.
